matrix~ feedback

Hi:
I trying to build a EMS Synthi like matrix modular synth. When I use matrix~ to route, for example, osc1 out to feed osc2 frec contr, everything on that path stops.
I think it’s something related to matrix~ signal looping issue, isn’t it? I cant’t figure it up. Any thougth?
symple patch follows.
thank you very much.

many thanks to everyone…
I already know couprie synthi… When I started this project it was the first (and only in max) I found.

but..

(refreshing an old topic) Im trying not to emulate, just creating something new.
As somebody said in this forum (I dont remember who), It’s a little bit useless to "emulate" analog synths digitaly cause its diferente nature.
Im trying to, in first place to get in touch with that analog modular technologies in a way cheaper and cleaner but not missing sigth that Im not working whit signals but samples.
Its just like a philosophic matter, isn it?
My goal is to reveal digital limitations bulding (in this case) analog like sinthesizers and to use it as an stetic resource.
What do you think?
